This is a most excellent place for technology news and articles.
This $100 box from Google runs on the same SoC as the $50 streaming box from Onn (Walmart). The only major differences are the Google box as 4GB of RAM vs 3GB, a 1Gb Ethernet port instead of 100Mb (both have WiFi 6), and the Google box has a USB Type C port for power/data and would need an OTG adapter/hub while the Onn box has a Type A and a barrel plug for power.
TBH, the biggest issue there is the 100Mb port on the cheaper box. That is actually too low to stream a quality high-bitrate video file.
